Is the article qualitative OR quantitative research?
What is the purpose of the study?
Does this research add to the literature? Is it a bigger, longer, more substantial study?
Is the hypothesis clearly stated?
Does the article include a literature review and cover related studies?
How are the study methods described?
Who was studied? Age, sex, ethnicity?
Who was not studied?
What size was the population studied? (ex. N value)
How was the population studied? In a clinical or real setting?
How long was the study?
What materials were studied? (i.e. drugs or devices)
Who funded the study?
What type of study was conducted?
How are the study results described?
Do the results include statistical analysis?
Are all results discussed, including unexpected results?
